Having an argument at work.
I THINK
5 square meters is 5 x 1 meter squares (imagine 5 massive flagstones that are 1m x 1m)
Then 5m2 is 5 meters x 5 meters (25 massive flagstones that are 1m x 1m)
MY BOSS THINKS
They are both the same
HIS BOSS THINKS
The opposite of what I said
Google and various other searchs come up with different answers. The other blokes in work can't agree.
What is the right answer

They're the same.
The "square" refers to area, area is always calculated based on length x depth.
I would guess one is an Americanism, but they're both the same.
5m2 doesnt equal 25m2, 5m2 = 5m2. Using your flagstone thing, both are 5No. 1x1m flagstones.
25m2 would require a 5x5square of 1x1m flagstones (or other variant)

So if you have a tile that is 1m x 1m and you call that 1 square meter. What do you call 5 of them?
I know you call it 5m x 1m really but you can see where the confusion lies.

5m2 is 5 meters squared, so, in it is an area within a set boundry it has a value of 5 metres.
So, you can have a 5m x 1m shape or 2.5m x 2m shape are any combination as long as the value of the numbers multiplied together comes to 5.

5x5 = 5 squared = 25
5x1 = 5
That's why I thought they were different.
My understanding was one was
5 lots of a square meter = 5^1 = 5x1 = 5
And the other was
5 x 5 lots of a square meter= 5^2 = 5x5 = 25
Now you have the m2 is ref area only it makes sense that they are the same as its not the number ^2.
We only say cubic m/cm etc when referring to volume, we don't say meters cubed! Probably is an Americanism mate
LankyIanB
03-07-12, 04:09 PM
m = measurement of length
m2 (2 should be superscript) = square meter (meter squared) = measurement of area.
1m * 1m = 1m2 - one square meter
1m * 5m = 5m2 - five square meters
5m * 5m = 25m2 - twenty five square meters

Basic maths fail!
I think the problem is coming from the language side though.
- a metre squared (m²) is a unit of length subjected to a mathematical function - in the case multiplied by itself. So a metre x metre.
- a square metre (in my mind) is a visual representation of the same. i.e. a square that has a side of length 1m.
The problem comes when you start putting squared metre - which is a term that I've never come across. Similarly a metre square (although if it's possible that seems less wrong).
Now I'm looking back at this post and I'm convinced I've spelt square wrong...:pukel:
I think we should make it easy and measure things in 2 steps by 3 steps etc.

it is down to the unit in this case m²
so 5m² is 5 instances of 1m²
5 square metre or 5²m is 5*5 instances of the metre unit = 25m which is a totally dimension. It is a single dimension whereas a m² is two dimensional
However, people use metre squared and square metre in the same way to mean m²

I think it's all in the "d".
5 squared metres = (5^2)m = 25 metres - not a common term though.
5 square metres = 5m^2 = 5 metres squared
But a room 5 metres square (no "d") would be a square room of side length 5m, which would be 25 metres squared.

5 square meters is 5 off 1m²
5m² can be any dimension that makes that area, whether that be a shape 5x1, 2.36x2.36, 1.667x3 or 1x5. It doesn't need to be square it could be a circle 142cm in diameter.
In terms of area they are the same, in terms of shape they can be very different.

Your maths is well out btw, I take it 'basic maths' doesn't extend to algebra? :p:D
But yes 5metered squared would indicate that the 5 was squared
But that would be 5^2 m.
Not 5m^2 which equals 5.
As m is the symbol for 1meter. So 1^2 =1
5*1=5.

A 5m2 square room if labelled as 5m2 indicates a floor area of 5m2, where you lot are getting confused is you're not looking at the significant bit at the end of the dimension (m2)

It's all a nonsense anyway. No matter what anyone thinks.... Ask anyone who works with maths / area daily, maths teachers, university lecturers, engineers, quantity surveyors, builders.
None of them would call an area 5m x 5m '5 squared metres' or anything similar. Yes there is some ambiguity in the language, but common usage is that area is defined by the number of times a 1mx1m square could fit into that area.
It would fit into a 5mx1m area 5 times therefore it is 5m.sq
It would fit into a 5mx5m area 25 times therefore it is 25m.sq

I'm afraid that although that might seem logical, it's not the way it's defined, nor what is taught about representation of units in GCSE and A level maths and physics, or degree level engineering.
"Metres squared" is a unit, written m². Just like 5 squared is 5².
Five squared, 5²
Metres squared, m²
get the linguistic logic here?
so 5m² is the same as five square metres.
What you're describing would actually be written 5²m² or (5m)²
It's a bit of a conceptual leap to think that you can square units as well as numbers. You can also do the opposite. "Per second" can also be written s^-1, literally "seconds to the power of minus one".

It is quite simple as I have said before you are talking about a unit that describes an area 1m * 1m. For convenience because it is 1*1 we simply call it a m². Instead of m² call it a 1metre flagstone/.

Listen to this man will you guys?
You are confusing the terms of mathematics and algebra
m = 1m
m2 = 1m2 = 1 metre to the power of 2 = 1 x 1 = 1
5m2 = 5 x (1 metre to the power of 2) = 5 x (1 x 1) = 5
5 to the power of 2 = 5 x 5 = 5 squared = 25
5 to the power of 3 = 5 x 5 x 5 = 5 cubed = 125
What matters is which integer you are applying the exponent to.
IT geeks like Tim and I understand this properly because it's the basis of binary numbering.

When I saw last week how the primary school were planning to teach my son to read and write (both at the same time, and entirely in phonetics, including the writing aspect) it suddenly dawned on me why so many young people can't spell.
"Toylet" being a perfectly acceptable spelling of "Toilet" and left uncorrected, because it was phonetically correct, therefore the teacher could understand it, and spelling would be taught separately at a later date. Not a problem for a primary school child to make spelling mistakes, but correct it and explain it at the time IMO, and if they don't get it, correct and explain it it as many times as is required, but don't let them get established in proficient in writing whilst spelling everything phonetically, then attempt to change it later.
I am resigned to the fact I'm going to have to fill in the gaps at at home.

Can we move onto my favourite one, how many bytes in a megabyte?
Can't be rrrsssed typing that one out, have a wiki link ;-)

If you hadn't done that, you wouldn't have a son...

mega, although very widely misused in the binary sense, is an SI prefix meaning 1 million. 1 megabyte = 1,000,000 bytes. The binary representation of 1 mebibyte (MiB) is 1x2^20 bytes or 1,048,576 bytes.

OK, I'm resigned to the fact I'll have to fill in more gaps at home than my parents had to fill in with me.
My son isn't going to get the same education at school as I got.

Ahem.
2 to the power of 20 = 1,048,576
"The binary approximation of the mega-, or 1,000,000 multiplier, which causes a change of prefix. For example: 1,048,576 bytes = 1 megabyte (or mibibyte).
This number has no special significance to computers, but is important to humans because we make use of powers of ten."

1 megabyte is most certainly not the same thing as 1 mebibyte.
btw... I knew somebody would bite (or byte) ;-)

I think from what the author of the wiki has written, he understands it, but you are being pedantic ;-)
When does misuse of a lingustic term become so common, that actually, it becomes the correct answer?

Puerile jokes aside, I totally agree with you. I've had many arguments with my kids over correct pronunciation and spelling and mathematics. I'm old school with regards to these things.
eg
12.17 is twelve point one seven, not twelve point seventeen
H is "aitch" not "haitch", never mind what your teacher says...
Mind you at primary school, I was taught that the primary colours were red, yellow and blue. They then scrap all this later on and teach that primary colours are red, green and blue, unless using subtractive method where its magenta, cyan and yellow. So where red, yellow, blue comes from, I've no idea.

Well, actually the reverse occurred. It was misused at the start when the error was fairly insignificant. As data volumes have grown it has made an enormous difference.
Pretty much all of the world standards bodies define it precisely. A binary prefix must be used to describe a binary quantity. Using an SI prefix is just incorrect, pedantic or otherwise.

No offense to any teachers here.... but even with the best staff in the world, if the system / guidelines are wrong then it's never going to work.
An ex of mine was a teacher and in her school (academy) she was told she wasn't allowed to mark-down / correct spelling because she wasn't an English teacher.......... so they only have to learn to spell correctly for the 10% of the time they're in English lessons(!)
While we're on the subject of abbreviations I did see this one the other day:
√-1 2³ ∑ π ...........and it was delicious!
Thought it was quite good.

red yellow and blue is correct.
yellow and blue make green but with green red and blue you can't make yellow.

CMY or RGB
RYB are the primary colours of absolutely naff all.
I'm really amazed people quote stuff for others to read without the vaguest understanding of the subject.
edit: the above is a bit harsh and I apologise. However it does kinda show how outdated 18th century theories make their way into people's heads because they are still taught at schools long after they've been proved wrong.

A long time since I needed that particular equation. Although I wish my son had used it before manufacturing generation 3 wilky. Or even better his girlfriend understanding it resolved to a boolean equation.

Called subtractive on your wiki page works plotter uses Cyan Magenta Yellow... but then again it prints onto white paper which is how we get white, the CMY combo cannot make white.
Primary colours RGB are what you need to make up any other colour by adding various ratios of the RGB selection.
Thats an explanation of my understanding of colours, but Im now not too sure what your original question actually was. :confused:
